JavaFX Loader not loading - javafx

Question

This is my Main Class:
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("mainmenu.fxml"));
primaryStage.setTitle("Horse Manager");
primaryStage.setScene(new Scene(root,400,600));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
And I am getting this error:
Exception in Application start method
Exception in thread "main" java.lang.RuntimeException: Exception in Application start method
at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:917)
at com.sun.javafx.application.LauncherImpl.lambda$launchApplication$155(LauncherImpl.java:182)
